If you're a React dev:
- GPT 5.6 Sol xhigh performs the overall the best
- GPT 5.6 Terra medium is the most bang for your buck
Claude Fable 5 performs on par with Sol but is on average 6x more expensive!

react.doctor rules are now in the React, Next.js and TanStack presets for ESLint and Oxlint!
The useful stuff: fewer unnecessary effects, better render performance checks, hydration catches, server component rules, security checks and framework-specific diagnostics.
Thanks a million, @milliondotjs 🙌
ALT Code snippet displays ESLint rules for React with error settings for various state management and rendering issues in a TypeScript format.

i'm building something that's very FAST and good at frontend tasks
it's like Lovable for localhost. you prompt → agent edits files on your machine directly
